Running Bodhi on a pen drive

Can anyone assist with a problem i'm having with a 32 bit version of Bodhi. I have the OS on one of those discs that you get with the Linux magazine, so in theory the OS should work and not be corrupted. I'm trying to run the OS on a USB stick [i can do it with Lubuntu] but Bodhi won't boot up. The error message is:

Busy box v1 27.2 (ubuntu 1:/27.2-2ubuntu3.2) built-in shell (ash)
Enter 'help' for a list of built-in commands (initrimfs) help

Many thanks
